The percent dissociation of ascorbic acid can be calculated using the formula for percent dissociation given the pH and pKa of the solution. The formula is: % dissociation = 100 / (1 + 10^(pKa - pH)). Plugging in the given values (pKa = 4.10, pH = 5.50), we get % dissociation = 100 / (1 + 10^(4.10 - 5.50)) = 96%. This indicates that 96% of the ascorbic acid is dissociated at a pH of 5.50.
